Step 1: Draw an imaginary figure by using the given measurements

          

Step 2: Recall the area of the sector formula  

            NOTE: \frac{\theta}{360} * \pi r^2

                   \pi r^2 =  Area of the circle


Step 3: First find the area of the circle

                 EXMAPLE:   \pi r^2 = 3.14 ∗ 4 * 4

                      

Step 4: Substitute all the values in the formula.

          EXAMPLE:   \frac{\theta}{360} * \pi r^2

                         \frac{30}{360} * 3.14 * 4^2


Step 5: Simplify the equation

            EXAMPLE:   \frac{12.56}{3} cm^2

                                 4.19 cm^2
